Description

How to reproduce the issue or how to test the changes

1. Go to Directorist > Locations and open an existing location from the taxonomy list.
2. Click Update without changing the location.
3. Confirm the success notice reads Location updated. Go to Locations rather than using the Categories fallback.
4. Click Go to Locations and confirm it returns to the Directorist location taxonomy list for the listing post type.
5. Open and update a Directorist category and confirm its existing category-specific label remains unchanged.

Verification completed:

• The exact LocalWP list → edit → update path displayed Go to Locations.
• The rendered link returned to edit-tags.php?taxonomy=at_biz_dir-location&post_type=at_biz_dir.
• The category taxonomy continued to expose its existing Go to Categories label.
• PHP syntax, targeted PHPCS, and git diff --check passed.

The reported PHPCS failure occurs in the inherited pull_request_target workflow before source checkout; the PHPCS step never runs. PR #2945 replaces that unsafe workflow with the fork-safe pull_request workflow. The changed PHP file passes the repository rules locally with zero errors.
